Video Transcript for Dexter Trailer Suspension K71-652-00 Review

Today we're going to be taking a look at the E-Z Flex Heavy-Duty Rubber Suspension System. This system is available for tandem axle applications with part number K71-652-00 and for triple axle applications with part number K71-656-00. This is going to replace standard trailer equalizers and leaf spring suspensions. It is designed for 1 3/4" wide double eye leaf springs. This system's going to deliver nice, smoother towing when compared to traditional leaf spring suspensions. It's got this nice rubber core that isolates and absorbs damaging road shocks before they hit the trailer frame and the contents.

The rubber core's going to last a long time and won't be affected by the elements. It's a very simple installation. It does not require any welding, cutting or grinding of the trailer frame, and it's going to include all the hardware necessary for your installation. It's also going to come with detailed installation instructions. The system is made from a nice, durable steel construction. It's going to feature a protective finish to keep everything safe from the elements so you don't have to worry about rust or corrosion building up.

The system also offers multiple grease zerk fittings for easy maintenance, so you can see on all of the bolt heads as well as the actual equalizer components, we're going to have those zerk fittings. That's going to keep everything well-lubricated and quiet at all moving components, so that's a really nice design of the unit. This is a direct replacement for the Dexter standard equalizer 13-104, so if your equalizer has that number stamped on it, then this will work great for your trailer. If you can't find a stamped number or you have a different brand of equalizer, then you will want to take a few measurements to verify that this system will fit your application. For instance, your axle spacing on your trailer must be 33" apart on center, so from the center of one axle to the center of the other, you need a separation of 33". The distance between the lower bolt holes on this system, that's this one right here and this one right here, is going to flex between 5 1/4" and 6 1/4" and the bolt hole diameters are 9/16th of an inch on the system. If the spacing of the holes on your equalizer is between those measurements, then this will work for your trailer.

The shackle measurement, measuring from one hole to the other, center on center, is going to be 2 1/4" apart, and this is designed for axles that have a capacity up to 6000 pounds. Really nice design, very strong and durable design. I just want to go over what it's going to come with. It's going to come with these four bolts right here. They all have grease zerk fittings on them, and it's going to come with the brass bushings for those. These do have the splines on them, so it forces into the mounting location.

Then it's going to come with the nuts to get everything tightened and secured. These are going to be designed for the end of the leaf spring that does not connect to the equalizer. Then you're going to get your equalizers. Again, it is available for tandem axle applications and for triple axle applications. You're going to have your center bolt. This is going to connect to the center hanger, bushings already included there, and you're going to have the nut to get that tightened down as well. Again, that's going to have the splines on it also. You're going to get all of your necessary shackles. The bolts on those shackles are already pre-installed, so you don't have to worry about that. The other end of your leaf spring's going to connect right here. It's going to come with a brass bushing. I just went ahead and loosely installed it all so you can kind of get a good idea of how the unit's going to work. It's also going to come with all the necessary hardware to get all that tightened down. That's going to do it for today's look at the E-Z Flex Heavy-Duty Rubber Suspension System.

I think they will be great. They are installed and I will be traveling soon on the new suspension. Thank you etrailer for youyr good products RV manufacturers are totally missing the boat and have absolutely no regard to quality in regards to the cheap suspension parts they put into these trailers. It just does not make any sense to put such cheap bushings. As far as I am concerned the whole RV manufacturing industry are very inconsiderate of there retail customers. 229233

I put this set-up on both my tandem boat trailer and a 7,000# enclosed construction trailer. Prio to the boat trailer was experiencing a blow-out virtually every other trip. Thought I had a tire problem. After rebuilding the suspension system... Blow-outs are a thing of the past. Trailer tracks extremely well in curves at high speeds. On the construction trailer I had a spring eye bolt fall out after installing this kit. I have no idea how or why but I always give the trailer a look over any time I stop. Did a mcGyver to get it back to the shop where I installed a standard suspension bolt. Been going that way ever since... 269088

I installed this Dexter E-Z Flex om my Keystone Cougar in about 5.5 hours in my driveway. I also installed the complete wet-bolt kit at the same time. I have taken many trips since installing this, including a trip from Cali to Yellowstone and back, and I have to say the quality of the ride has improves so much that it is near perfect! The rough roads and pothole are handled so much easier and I have less fatigue at the end of each days drive. Getting under the rig to lube these has been very easy and keeps things smooth and quiet. Do this upgrade! You won't be disappointed! 323299

The installation is pretty straight forward, however with the trailer weigh and spring strengths it was quiet a lot of work. I have air tools and jacks to work with and it took about six hours. Didn't realize how bad my bushing were worn until it was apart. Camper is a 2013 with about 15000 miles and the plastic bushing were considerably worn. With E-Z flex installed, all the creaking noise is gone, tows a lot smother, still some chucking, but well worth the money and time. Great product and great service from etrailer. Thanks 267849

About as simple a swap as you could expect. Tear off all your old stuff, throw all the new stuff on and voila! A couple of floor jacks, and 2 hrs max. Great time to swap out your junk Chinese wheel bearings too. No major ride change or anything, but at least I know the links aren't going to fail like the OEM ones did. See pic. 285667

This product is a nice upgrade for my travel trailer suspension. The normal suspension has a solid equalizer, plastic sleeves in the spring ends, and much thinner shackles. This system has the cushioned equalizer, bronze bushings for the spring ends, greasable bolts, and heavy-duty shackles. More importantly, you can instantly feel that the trailer tows smoother. I used to feel all four axles crossing an expansion joint; now I can't feel the trailer at all. 149788

Excellent product, I bought these to replace the equalizers that came stock on a new 10,000 lb rated 2014 car hauler that is on the road every day . At the time we bought the equalizers from etrailer, the stock equalizers had already been replaced 3 times. 5 stars ......... well worth the money, easy installation, reduced maintenance would definitely recommend to anyone using a heavy duty trailer every day. 241219

Went together quicker than anticipated. I reset the axles to the top of the springs at the same time so it took a little longer. Probably 6 hours total, but I wasn't rushing. Have to do a little welding, too. Much heavier duty product than original equipment. Just did it yesterday and haven't towed trailer yet, but believe it will be a smoother ride and components will last much longer. 272575

Would have loved to write a great review as the product appears to be well built and I like the ability to lube all the spring shackles. Unfortunately one of the bolt patterns does not fit my trailer. It would help if ALL the bolt hole measurements would be displayed in one place - so that you would know prior to ordering if things would fit. 234003

Product was easy to install, Brand name parts front the same manufacturer as the original equipment, this is the second time I have purchased from etrailer and I will continue to use them for all my Rv parts replacement needs, the pin box I purchased from etrailer weighed over two hundred pounds and shipping was free 202658

Probably the best upgrade I could make on my 18 foot car hauler. The shackles are now very robust and the grease-able bolts are fantastic. Etrailer helped me with my order, got the order right the first time and followed up with emails. I am very pleased with etrailer and would highly recommend them for everyone. 255492

by: Larry07/28/2015


All of the parts are of high quality and went together easily. Some modification to the hangers may be necessary to allow for the equalizer to move freely and not damage the rubber damper. Overall this is a significant upgrade to the standard equipment and well worth the price. 214949

Beefy! I like this and it should be OEM on all new RV suspension systems! If you don't have it, buy it. If you have reasonable "garage" skills this is easy to install. I suggest if you install these that you cover during storage to protect damper material from UV damage. 306770

The item looks good but I am waiting on the springs to get here before I break down the assembly and install them. I live on the OBX of NC and I don't want to get caught with my RV apart and not able to get out. 194299

Review from a similar Dexter Axle E-Z Flex in Trailer Suspension


Great service, questions answered promptly and accurately, package arrived before the promised time. I had no problems installing the product as the fitment was exact thanks to etrailer product recommendation. Installation of this item should be done by an accomplished mechanic and in a well equipped shop. My 5th wheel is 32' long and the installation requires at least 3 jacks to lift the trailer and axles and to manuver the axle height in order to install the pivot bolts. Product smoothed out ride to some degree but the reason for my installation was due to worn out bushings which made a click/pop noise while driving over uneven surfaces. 234675

Review from a similar Dexter Axle E-Z Flex in Trailer Suspension


This is probably one of the best products you can buy when fixing up a trailer where everything is egged out and wasted. Bear in mind that all spring hangers need to have the same dimesnsion from the bottom of the frame to the center of the holes. I didn't know this until the instructions revealed that. If your center hanger is tall, and end hangers are short, your springs will sit at an angle. So, provided all your hangers are the same, it's a quick swap. If they don't match, there will be welding required as well as a bunch of measuring and fabrication. 315219

  • Fit of Dexter # K71-652-00 E-Z Flex Suspension Equalizer as Replacement for 13-104-02
  • The Dexter Heavy Duty 5-5/8 Rubber Suspension Equalizer, part # K71-652-00, is the specified replacement part for the standard 13-104 equalizer for tandem axle trailers. This is intended for use with axles rated for up to 6000 lbs. Please take a look at the linked photo that shows you the normal range of the spacing between the shackle bolt holes.

  • Can E-Z Flex Heavy Duty Rubber Suspension System # K71-652-00 Replace # TREQ356
  • There is a dimension difference between the equalizers you currently have and part # K71-652-00. I have attached drawings of the # K71-652-00 and the equalizers you currently have, part # TREQ356. As you can see the difference in the distance between the two attach holes on the bottom of the equalizer is 1/2 inches. With that being split between two springs that would be approximately 1/4 inch difference on each spring. You may find that you need shackles that are a bit longer. The height...

  • How to Measure Trailer Equalizers to Determine Replacements
  • To know if the # K71-652-00 will fit your trailer you will need to take a few measurements of the equalizers that you currently have on your trailer. The E-Z Flex Heavy Duty Rubber Equalizers, part # K71-652-00, that you referenced have the following measurements: Bolt hole diameters of 9/16 inch From center of bolt hole to center of bolt hole 5-1/4 to 6-1/4 inches wide From center of bolt hole to center of bolt hole 2 inches tall See the picture to the right to see a picture...

  • Suspension Upgrades for Tandem 3,500 Pound Dexter Axles on a Jayco Travel Trailer
  • E-Z Flex Heavy Duty Rubber Suspension System # K71-652-00 is designed for axle capacities up to 6,000 pounds. So if your measurements are close to those of this system you can use it. This system was designed to fit in place of equalizer # TREQ104 (13-104). Check your equalizers for the part number or just go by the measurements. Other option to improve the ride of the trailer is to use a shock kit such as # LC281255 for 2-3/8 inch diameter round axles or # LC281281 for 3 inch diameter...

  • Curved Equalizer # TREQ356 Recommendation for a 2004 Wildcat 5th Wheel Trailer
  • Based on the measurements that you gave you would want a TruRyde Curved Equalizer, part # TREQ356.

  • How Often Should Dexter EZ-Flex Equalizers Get Greased
  • I spoke to my contact at Dexter and he informed me that they recommend greasing the E-Z Flex equalizers every three months or 3,000 miles. I also attached a pretty helpful guide to how often trailer components should be maintained. For grease Dexter recommends wheel bearing grease. For that we recommend the red grease part # L11390.

  • Lippert has Equa-Flex systems for 5.2K axles, # LC257486-2, and 4K to 6K axles, # LC1594011, but not for 3,500 pound axles but I do have a possible option for you. Dexter has EZ-Flex system # K71-652-00 that works with up to 6K axles. If your current equalizers are 5-1/4 to 6-1/4 inches long (measured from the center of one eye to the center of the other eye) with an axle spacing of 33 inches on center then you can use this kit. Another option is to use a shock kit # LC281255 which...

  • How to Determine the Right Replacement Equalizer for a Horse Trailer
  • To find the proper replacement equalizer for your horse trailer you will need to take a couple of measurements. Measure from the center of the front hole to the center of the rear hole. Then measure from the center of the top hole down to the center line between the 2 lower holes. I have included a picture that shows the measurements needed. The standard equalizer is 7-3/4 inches long but the E-Z Flex will fit in place of 7-1/4 to 8-1/4 inch long equalizers.I have also included a link...

  • Availability of Dexter E-Z Flex Suspension System For Trailer with 34 Inch Axle Spacing
  • All of the equalizer suspension enhancements I have for double-eye springs are designed to fit either 33 inch spacing ( # K71-652-00) or 35 inch spacing ( # K71-653-00) between axles. I do not offer any that are listed for a 34 inch axle center spacing. You might want to measure the distance from the center from one bolt hole to the center of the other bolt hole on your existing equalizer. If you get between 5-1/4 and 6-1/4 inches you could use the Dexter E-Z Flex Suspension System,...

  • 2003 Gulfstream Mako 28FRBH
  • In order to find the correct equalizers that will work for your trailer you will need to take a few measurements of the equalizers you wish to replace. I have attached a drawing that shows what dimensions you will need. Examples of typical measurements needed as noted on the attached drawing: A = Length from center of left-most eye to center of right-most eye B = Length from center of left eye to center of middle eye C = Diameter of center eye hole D = Diameter of...

  • How to Pick Out EZ-Flex Equalizers for a Trailer
  • The Dexter E-Z flex systems fit specific applications. You are going to have to measure your current equalizers to find the correct one. The part # K71-653-00 is a replacement for a 7-3/4 inch equalizer and the part # K71-652-00 is a replacement for a 5-5/8 inch equalizer. You will need to measure the dimensions of your equalizer to see what would work. I attached an install video for you to check out as well.

  • Rubber Equalizer Troubleshooting on a 2008 Keystone 344J Everest 5th Wheel Trailer
  • I did some research and found that your trailer is rated at well over 14,000 lbs. so the correct replacement equalizers would be the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 7-3/4 inch Equalizers, item # K71-653-00. The part you mentioned, item # K71-652-00, is for up to 6,000 pound capacity trailers and would be too light for your Keystone Everest trailer. Depending on your gross trailer weight, loaded and ready to tow, the # K71-653-00 may also be too light for...

  • Comparison Between Dexter E-Z Flex Suspension System and The Lippert Equa-Flex Equalizers
  • Both the Dexter E-Z Flex Heavy Duty Rubber Suspension System, # K71-652-00 and the Lippert Euqa-Flex Cushioned Equalizers, # LC1594011, are upgrades from the traditional leaf spring suspension equalizers. Both the Dexter and Lippert systems use rubber shock technology that will deliver smoother towing. The Dexter E-Z Flex has a spring end spacing that runs between 5-1/4 to 6-1/4 inches. The Lippert Equa-Flex dimensions on the spring end mounting holes is 5-1/2 inches. The Dexter E-Z...

  • Are Rubber Style Suspension Equalizers Available for a 7,000 lb Tandem Axle Car Trailer
  • It is possible that we have a rubber suspension equalizer that can be added to your 7,000 lb tandem axle trailer. The axle spacing will be needed to determine which rubber equalizers, if any, will work on your trailer. This style of equalizer is designed for trailers with two 3,000 to 8,000 pound axles, depending on which setup is needed. If your axle spacing is 33 inches on center the E-Z Flex Heavy Duty Rubber Suspension System, # K71-652-00, would be the correct equalizer system for...

  • Raising Suspension of 2008 Keystone Outback 25RSS
  • The Dexter E-Z Flex Heavy Duty Rubber Suspension System you referenced, part # K71-652-00 replaces your existing equalizer like part # TREQ104. The rubber spring will isolate road shock and improve the ride of your trailer, but it will not raise the height of your trailer. If your leaf springs are currently connected to the underside of your axle, you can use an Over-Under Conversion Kit like part # K71-384-00 for a 2-3/8 inch diameter axle or # K71-385-00 for a 3 inch diameter axle...

  • Upgrading Lippert Equalizers with a Dexter EZ-Flex System on Lippert 2,500 Pound Axles
  • You are right, none of the EZ Flex systems or EquaFlex systems have the proper measurements or range to fit in place of 6-3/4 inch equalizers but I do have an alternative solution for you. You could install a shock kit # LC281255 if the axles are 2-3/8 inches in diameter. If that will not work then to use the EZFlex system you would have to move the front hanger forward 1/4 inch and the rear hanger back 1/4 inch in order to get to the widest measurement compatible with system # K71-652-00....

  • Dexter E-Z Flex Equalizer System for a Keystone Cougar 5th Wheel Trailer
  • To determine if a Dexter E-Z flex system will work on your trailer you will have to go by the equalizers currently used on your trailer. Measure the distance from the center from one bolt hole to the center of the other bolt hole on your existing equalizer. If you get between 5-1/4 and 6-1/4 inches you could use the Dexter E-Z Flex Suspension System, part # K71-652-00. If you get between 7-1/4 and 8-1/4 inches you could use the Dexter E-Z Flex Suspension System, part # K71-653-00. Using...

  • Dexter E-Z Flex Rubber Suspension System # K71-653-00 Fitment on 2005 Outback 28RSDS Trailer
  • The Dexter E-Z Flex Heavy Duty Rubber Suspension System # K71-653-00 is designed to be used with 35 inch axle spacing and a 8,000 lb capacity specification. On your trailer, if you measure the distance between the center of one axle to the center of the next axle it needs to measure 35 inches. The axle capacity needs to be 4,000 lbs. or less per axle. If you have 33 inch axle spacing you can use the Dexter E-Z Flex Heavy Duty Rubber Suspension System # K71-652-00 and it has a 6,000 lb...

  • Recommended Suspension Improvement On 2008 R-Vision Travel Trailer To Improve Ride
  • To improve the ride for your R-Vision travel trailer I recommend the Lippert Components Bolt-On Shock Mount Kit, part # LC281255. With the oil shocks, it will cushion the ride and make the ride smoother. This kit comes with all the hardware needed for installation. I would invest in one item like the # LC281255 first, and see if you notice a lot of ride improvement. If you are still not happy with the ride, you could add the Equalizers for E-Z Flex Heavy Duty Rubber Suspension System,...

  • Cushioned Equalizer Kit for a Tandem Axle Trailer Trailer with 5200 Pound ALCO Axles
  • You may be able to use the E-Z Flex kit # K71-652-00. This kit fits if the tandem axle spacing is 33 inches and if the equalizers are # TREQ104 or have the same measurements. The measurements can be seen in the picture I have included. The E-Z Flex equalizer will actually fit in place of 5-1/4 inch to 6-1/4 inch long equalizers.

  • Can Dexter E-Z Flex Suspension System # K71-652-00 Replace Lippert Equa-Flex # LC1594011
  • Both the Dexter E-Z Flex Suspension System # K71-652-00 and the Lippert Equa-Flex # LC1594011 will work with double eye tandem axle suspensions up to a 6K rating. The E-Z Flex is compatible with a spring end spacing of 5-1/4- to 6-1/4-inches and since the dimension of the holes on the Equa-Flex is 5-1/2-inches (see linked photo) the Dexter will fit in its place. I recommend replacing both units on the trailer to ensure consistent performance.

  • Can E-Z Flex or Equa-Flex System Fit a Trailer that Uses Q310 Equalizers and 5K Axles
  • The E-Z Flex system # K71-652-00 will work but it is 1-3/4 inches shorter than the equalizers that you have now. The height will be lowered a little (not that full 1-3/4 inches though because the other hangers in the system will remain at the same height). The Equa-Flex system # LC1594011 is less likely to fit since they are 5-1/2 inches long which is more than 1/2 inch shorter than the equalizers you have now.

  • Will the E-Z Flex Equalizers # K71-652-00 Fit on a 2006 Laredo 29RK With 5000 lb Tandem Axles
  • The E-Z Flex Suspension Kit, # K71-652-00, will work on trailers that have axles rated up to 6,000 lbs each. Your 5,000 lb axles fall within the capacity of these equalizers so the weight would not be an issue. These equalizers are also compatible with your 1-3/4 inch leaf springs, but you will want to make sure they are a compatible replacement for your current equalizers. The E-Z Flex equalizers were designed to replace the standard Dexter equalizers # 13-104. This number should be...
